Here is what to expect from Tropical Storm Debby in Massachusetts, Rhode Island and Connecticut

Debby is certain to impact southern New England. Here is what the experts are saying.

According to the NOAA, Debby is expected to produce potentially historic rainfall totals of 10 to 20 inches, with maximum amounts of 25 inches, bringing areas of catastrophic flooding across portions of the eastern half of South Carolina, and southeast North Carolina through Friday.

From northern North Carolina through portions of the Mid-Atlantic States, 4 to 8 inches of rainfall, with local amounts to 12 inches, are expected through Sunday morning. This rainfall will likely result in areas of considerable flash and urban flooding, with river flooding possible.

An additional scattered 1 to 2 inches of rainfall, with maximum amounts of 4 inches is possible across western portion of the Central Florida Peninsula and southeast Georgia today which may aggravate any ongoing flooding conditions across that vicinity.

Currently, Massachusetts, Rhode Island, and Connecticut are expected to see at least 2 inches of rain into Sunday evening, with southern parts of those states possibly seeing as much as 6 inches.

Flash flood risk in southern New England is slight at at least 15%.

Wind is currently not expected to be much of a factor in southern New England compared to what you would expect with a tropical storm with sustained winds of 5-10 mph and gusts near 30 mph.
